You must follow all transformer repairing guidelines shared in this article to make your device ideal for functions. Have you ever thought why the noise comes or what’s the reason behind noisy transformer? There are two major reasons behind noisy transformer-

1. Magnetostriction

It is a random movement of separate sheets inside the stacked core. These sheets expand and contract at distinct rates when the core magnetized. The process of expansion and contraction occurs twice while alternating current flowing cycle completes through the coil.

2. Mechanical Abrasion

Vibration usually occurs when the core is transferred to everything else attached to it.

How To Fix The Issue?
The best possible way to fix noisy transformer is to reduce flux density by raising the steel amount inside the core. However, this is the most expensive yet effective method you can opt for repairing your transformer.

Just in case you can’t afford the above method, you can alternatively use a suitable adhesive between lamination layers. This is cheaper way to fix noisy transformer but it also adds extra step in stacking the core.

You need to assure that the lamination sheets are free of contaminants and do not have oil residues.

The least expensive method is yet to come- you can apply a low viscosity epoxy or polyurethane product for laminating the edges inside the stacked core. This is one of the fair and inexpensive methods used by most users to repair transformer noise. The concept is to bond the individual lamination sheets together to cut down the movement and the extent to which they can extent or contract while magnetism of core.

All these transformers repairing tricks are initially shared by leading transformers manufacturers company India. You can try out any of these suitable ways to repair your noisy transformer and get it back at perfect functioning state.
